Specification of Letters Patent.

HOSE-CLAMP.

Patented May a, 19111.

Application filed October 28, 1910. Serial No. 589,513.

ToaZZ whom it may concern:

Be itknown that I, ANDRE G. CATELAIN, citizen of the Republic of France, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hose-Clamps, of which the following is a specification.

My invention relates to clamping devices and has particular reference to means for attaching elastic hose to a pipe or nozzle, being also adapted to be used for coupling the ends of two sections of hose together by clamping them upon a connecting pipe or nipple.

The chief objects of the improvements which constitute the subject matter of this application for patent are :to provide a band clamp that can be readily applied to a. hose and firmly secured thereto with sufficient pressure to form an eifectiveconnection, and to produce a strong, simple and effective clamp that will insure a close contact throughout the entire circumference of the embracing member.

An important feature of my invention is the advantage to be derived from the special form of the clamping band employed, which is intended to be furnished in rolls from which the desired sections'required for a given coupling may be readily cut, so that the device will be convenient for clamping hose of any size. The bands which I use are made of uniform size throughout their entire length, requiring no special forming except to produce a series of longitudinal spaced slots which render the band more flexible when of a given gage, and facilitate the location of the clamping mechanism at practically any place in the band, thus conducing to economy in the manufacture and use of this part of the clamp.

able results by employing the devices illustrated in the accompanying drawing which forms a part of this application, and in which the details of construction are disclo ed in the following views Fi ure 1 is a side elevation of a i e and attached hose to which my improved band clamp is applied; Fig. 2 is an end view of the structures shown in Fig. 1; Fig. 3 is a plan view of a portion of the band strip; l ig's. 4 and 5 are views showing the tensioning lug. seen from different directions, and Fig. (3 is a detail showing the T-bolt and attachments.

I firmly upon the hose by I, accomplish the above and other desir ness. This band is furnished with suitable slots 13, arranged at spaced intervals along the-median line. The ends of the band are folded ordoubled back upon the main portion forming attaching eyes or loops 14.

' Une of said loops is engaged by the head 15 of a T-bolt 16, through one of and is provided the body of which projects the slots 13 in the band 12, with a wing thumb nut 17.

Slidably mounted on the boltbeneath thev nut is a washer in the form of a sleeve 18.

The other eye or loop 14 is engaged by a cylindrical lug 19 having its ends reduced to fit the loop, the central portion 20, thus left of'full diameter to form an integral collar, which projects through a slot in the band and prevents the lug from becoming displaced when the bolt is removed. The 001-.

lar 20 is furnished with a slot or notch 21 to receive the stem of the bolt 16.

To apply this clamping device a band is provided of suflicient length to nearly twice encircle the hose at the point of application, and the ends doubled over to form the loops 14. The lug 19 is inserted in one of said loops so that the collar 20 will engage a slot 13 and the head of thebolt made to engage the opposite loop as shown. The body of the bolt is then placed in the slot in the said collar, and the nut screwed down against the washer which passes through the slot 13 and engages an annular recess or seat 22 formed in the said collar 20. It will be readily seen that the band can be clamped further turning the thumb nut. In order to bridge over the gap between the loops 14, a bearing plate 23 is placed beneath the band atthis point, thus insuring an even pressure at every point around the periphery of the hose.

It will be seen that it will not be necessary to unscrew the nut entirely from the bolt when removing the clamp, as the bolt can be swung upon its pivoted head to release it froinits engagement with the lug 19 by loosening the nut suli'iciently to permit the washer to'become disengaged from its seat.

Other ways of applying my improved band clamp will be readily suggested to one skilled in the art. For instance, one band Having thus described myinvention What I claim as new, is

1. In a hose clamp, the combination of, a slottedband having its ends folded over to form loops, a T-bolt engaging one of said loops, a lug reinovably en aging the other loop, a notch in said lug adapted to receive the body on said bolt adapted to engage said lug.

2. In a hose clamp, the combination of a flexible slotted band having its ends bent to form loops, a bolt having a cross head engaging one of said loops, a lug engaging the opposite loop, a slot in said lug adapted to receive the body of said bolt, a clamping nut on said bolt, and a Washer on said bolt adapted to in the band and engage a said lug.

3. In a hose clamp, the combination of a band provided, with a series of longitudinally arranged spaced slots, and having its ends folded to form attaching loops, a bolt having a cross head engaging one of said loops, a lug engaging the other loop, a collaw on said lug engaging a slot in the band,

suitable seat in of said bolt, and a clamping nut project through one of the slots a notch in said collar adapted to receive the body of said bolt,- a nut on the, bolt, a washer for the said nut adapted to project through a slot in said band and engage said lug, and

a bearing plate arranged beneath said band. 4. In a hose-clamp, a strip of fiat flexible material having a plurality of openings formed therein andbent to form an encircling band, the ends of said strip being free and arranged on the under side of the body of the band, and means for drawing together the ends of said band, said means comprising a bolt detachably connected with said band, and a nut mounted on said bolt.

5. In a hose-clamp, a strip of flat flexible material having a plurality of openings therein and bent to form a hose encircling band terminating in loops with the ends of said strip free, and means for connecting said loops, said means comprising devices engaging said loops, a bolt engaging said devices and a nut threaded on said bolt.

In testimony whereof I aflix my signature in the presence of two witnesses.
